PWM: Pulse Width Cross-Modulation (from the other Oscillator) select button. When ON, the
width is controlled by the waveform of the other oscillator. This results in a very rapid change in
harmonics, close to the ring modulation effect. If no other wave form are selected, when ON,
this button let the oscillator to output a width controlled pulse with the same algorithm than the
Synthex.
Note : The MiniSyn'X benefits from the last Xils-lab researches regarding Oscillators PWM
emulation. The new algorithms developed during the two last years improve a lot the punch and
clarity of the PWM compared to the Syn'X v1.0, and other soft synthesizers. Without entering into
too much technical matters, the PWM algorithms are usually confronted to the same kind of
challenge that the problem known as ODF filters in the digital domain. The new Xils-Lab Sync
algorithm, while still not perfect, adds a lot to the overall perception of the PWM in the miniSyn'X.
R.M: Ring Modulation circuit select button. This modulation can be used to produce metallic or
bells sounds, depending on the waveform selected.
WIDTH: Pulse Width Control (for the pulse but also the triangle or the sawtooth wave form
depending on these latter settings). This knob controls the pulse width of the pulse waveform,
but also the triangle leading edge or the double pulse of the sawtooth, depending on which
waveform, triangle or sawtooth you have selected.
LEVEL: Individual Oscillator Volume Control (before the filter)
Sawtooth Label: Select a pulse width sawtooth waveform (a double edge according to the
width is generated)
Triangle Label: Select a pulse width triangle waveform (the leading edge of the triangle is
dependent on the pulse width)
